cyanogen chloride
C2Technical/Scientific, Military
Definition
Meaning
A highly toxic, colourless, volatile chemical compound (CICN), used as a chemical weapon.
A chemical intermediate and a potent irritant with effects similar to hydrogen cyanide; also known by its chemical warfare designation CK.
Linguistics
Semantic Notes
The term is compound, linking 'cyanogen' (a radical containing carbon and nitrogen) with 'chloride'. It denotes a specific chemical entity, not a class of substances.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation as 'хлорид цианогена' which is less standard. The established term is 'хлористый циан' or 'хлорид циана'.
Common Mistakes
- Mispronouncing 'cyanogen' (it's 'sy-AN-o-jen', not 'sigh-an-O-gen').
- Confusing it with hydrogen cyanide (HCN), a related but distinct compound.
- Using it as a countable noun (e.g., 'a cyanogen chloride' – incorrect).

FAQ
Frequently Asked Questions
No. While it shares similar toxic mechanisms (interfering with cellular respiration), cyanogen chloride (CICN) is a distinct compound from hydrogen cyanide (HCN). It is more irritating to the eyes and lungs.
Encounters are extremely rare outside controlled laboratories, specific chemical industries (e.g., synthetic rubber, pesticide production), or military contexts. It is not a household chemical.
It is a systemic toxic agent, meaning inhalation or absorption causes whole-body poisoning, similar to hydrogen cyanide, but with added severe irritant effects on the eyes and respiratory tract.
The stress pattern (sy-AN-o-jen) and the vowel sound in the first syllable (/saɪə/) differ from more common words like 'cyan' or 'cycle'. The 'o' in the third syllable is a weak schwa sound.
